The Maple Leafs, on scoreboards (3)
I believe the answer is:
tor
'the maple leafs on scoreboards' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tor that I've seen before include "Rocky prominence" , "Hill or rocky peak" , "Rot on a peak in Devon" , "Feature of Dartmoor" , "(Dartmoor) rocky hill" .)
